Solariz Healthcare Private Limited challenged an order dated 28.10.2025 passed by the Senior Examiner of Trade Marks (Mumbai Branch) concerning its Trade Mark Application No. 4826903.

Merck Sharp & Dohme B.V v.The Union Of India
Merck Sharp & Dohme B.V challenged the issuance of an impugned notice based on the fourth pre-grant opposition, arguing that the delay in deciding previous oppositions was causing undue hardship and delaying the grant of patent for its compound acalabrutinib (Calquence). The court directed the Patent Office to decide all pending pre-grant oppositions within a stipulated time frame and ensure any new opposition raises fresh grounds.
Amara Raja Energy And Mobility Limited v.The Registrar of Trade Marks
The appeal challenged the rejection of an application (No. 5547423) by the Registrar of Trade Marks on the ground that it was deemed abandoned due to non-filing of a counter statement against opposition No. 1323716. The appellant argued they were never properly served with the notice of opposition, as proof of actual receipt via email was lacking. The Court held that without proof of actual receipt, the time limit for filing the counter statement does not run, and consequently, the application cannot be deemed abandoned.

E.R.Squibb & Sons Llc v.Union of India

The Madras High Court dismissed the writ petition, holding that since the recommendation is only a suggestion for the Patent Authority, the petitioner could raise these objections during the final decision-making process or appeal.
Versuni Holding Bv Trading As Preethi v.Maya Appliances Private Limited
This Madras High Court judgment addresses the maintainability of a patent revocation application filed by Versuni Holding Bv Trading As Preethi against Maya Appliances Private Limited. The core issue was whether the petitioner could file this separate revocation petition when they had already contested the validity of Indian Patent No. 351954 as a counter-claim in an infringement suit before the Delhi High Court. The court held that once a defense is exercised in one forum, it cannot be re-agitated in another.
Gibraltar (Uk) Limited v.The Registrar Of Trade Marks
Gibraltar (Uk) Limited appealed the rejection of its trademark application for 'PROMAX' under Class 31, arguing that it was a prior user and should be accepted despite objections based on similarity to existing marks. The Madras High Court upheld the Registrar's decision, finding that the appellant’s mark was deceptively similar to cited marks already registered in the same class. The court emphasized that registering the single word 'PROMAX' would create an undue monopoly over a common formative mark.

The writ petition was filed seeking direction to accept and process an Indian Patent Application (IN202447028876) after the statutory deadline for filing a request for examination lapsed.

Dr.Vishwanath Padmanabhan v.The Joint Controller of Patents & Designs, Head of Office, Patent Office Chennai
Dr. Vishwanath Padmanabhan challenged the Patent Office's decision to deem his invention application withdrawn under Section 11B(4) due to a technical uploading error in the e-filing portal. The court found that since the petitioner intended to proceed and had paid all requisite fees, the rejection was unjust.
Dasaprakash Restaurant And Ice Cream Parlour Pvt.Ltd. v.The Deputy Registrar of Trademarks
The Madras High Court dismissed an appeal filed by Dasaprakash Restaurant and Ice Cream Parlour Pvt.Ltd., which sought to record its rights as a subsequent proprietor of the 'Dasaprakash' trademark. The court upheld the Trademark Registry's rejection, ruling that the transfer agreement was void ab initio because it was executed while the original proprietor, Balakrishna Rao, was legally incompetent due to insolvency proceedings. Furthermore, the court emphasized that since the mark was a family mark jointly owned by legal heirs, no single proprietor could unilaterally transfer rights.
Italfarmaco Spa v.Deputy Controller of Patents & designs
Italfarmaco Spa filed an appeal challenging a previous order by the Deputy Controller of Patents & Designs rejecting the grant of patent for Application No.10810/CHENP/2012. The High Court examined whether the Original Side Appeal was maintainable under Clause 15 of Letters Patent, considering the provisions of the Commercial Courts Act.
Italfarmaco Spa v.Deputy Controller of Patents & designs
Italfarmaco Spa filed an appeal challenging the order passed by the Single Judge of the High Court of Madras. The core issue was whether this Original Side Appeal (OSA) was maintainable under Clause 15 of the Letters Patent, given that the underlying matter involved a decision made under Section 117A of the Patents Act, 1970. The court held that since the Commercial Courts Act is a special enactment and provides specific appeal mechanisms, the intra-Court Appeal under Clause 15 was not maintainable.
Italfarmaco Spa v.Deputy Controller of Patents & Designs
Italfarmaco Spa filed an appeal challenging the order passed by the Single Judge of the High Court of Madras. The core issue was whether this Original Side Appeal (OSA) was maintainable under Clause 15 of the Letters Patent, given that the original matter involved a rejection of patent grant under Section 15 of the Patents Act, 1970. The court held that since an appeal mechanism already existed under Section 117A of the Patents Act, the intra-Court Appeal under Clause 15 was not maintainable.
Stove Kraft Limited v.The Registry of Trade Marks
The Madras High Court allowed Stove Kraft Limited's appeal against the Trade Mark Registry's refusal to register the mark 'Pigeon'. The court found that the appellant had presented prima facie evidence of prior consent terms with Pigeon Corporation, which warranted further consideration rather than outright rejection. Consequently, the registry was directed to accept and advertise the trademark application, allowing any objections from third parties to be addressed later on their merits.
Ms Sapco Laboratories Private Limited v.The Registrar of Trademarks & Glenmark Pharmaceuticals Limited
The Madras High Court heard an appeal challenging the refusal by the Trademark Registry to grant registration for 'BREMONT-L' due to opposition from Glenmark Pharmaceuticals ('GLEMONT'). The court acknowledged the appellant's arguments regarding common industry usage (e.g., the suffix 'MONT') but refrained from making a final decision on the merits of similarity. Instead, the High Court set aside the Registry's order and remitted the matter back for fresh examination, allowing the appellant to submit additional evidence while ensuring the opponent gets a chance to respond.
P.G.Purushan (A) P.G Purushan v.The Registrar of Trademarks
The Madras High Court allowed an appeal filed by P.G. Purushan against the Trademark Registry's decision to reject their trademark application, 'STIMULAID.' The core issue was whether the applicant had abandoned the mark after failing to comply with initial examination report directions. The Court found that since the appellant had submitted Form TM-M and attended subsequent hearings, there was no evidence of abandonment. Consequently, the rejection order was set aside, compelling the Registrar to proceed with considering and potentially accepting the application.
Titan Company Limited v.The Controller of Patents & Designs
Titan Company Limited appealed the rejection of its patent application for 'A Jewellery Assembly' by the Controller of Patents & Designs.

The High Court set aside the impugned order, finding that the respondent failed to consider the appellant's technical submissions.
P.G.Purushan (A) P.G Purushan v.The Registrar of Trademarks
The Madras High Court allowed an appeal filed by P.G. Purushan against the Trademark Registry's decision to reject their trademark application, 'STIMULAID.' The core issue was whether the applicant had abandoned the mark after failing to comply with initial examination report directions. The Court found that since the appellant had submitted Form TM-M and attended subsequent hearings, there was no evidence of abandonment. Consequently, the rejection order was set aside, compelling the Registrar to proceed with considering and potentially accepting the application.
Mir Mahamood Ali & Ors. v.Mir Mukkaram Ali
The Madras High Court ruled in favor of the petitioners, ordering the expungement of the respondent’s name from the Copyright Register. The dispute centered on a conflict where the respondent was incorrectly listed as the owner of the artistic features of the 'Sagar Homeo Stores' trademark, despite the petitioners being the rightful owners. By establishing their prior and valid registration with the Trademark authority, the court found the opposing copyright entry to be illegal and concocted.
M/S. Tvs Motor Company Limited v.The Assistant Controller of Patents & Designs, Patent Office
TVS Motor Company Limited appealed an order by the Assistant Controller of Patents rejecting its application for "Vehicle Frame Assembly" on grounds including lack of inventive step, exclusion under Section 3(f), and formal requirements.

The High Court set aside the impugned order and remanded the application for reconsideration.
M/S. Tvs Motor Company Limited v.The Assistant Controller of Patents & Designs, Patent Office
TVS Motor Company appealed an order rejecting its patent application for a 'Vehicle Frame Assembly' due to lack of inventive step and other objections.

The High Court set aside the rejection order and remanded the application for reconsideration.
